The brewing techniques described in this book are the same as Bill Owens used at his brewery. Bill's six barrel brewhouse uses the same tower (gravity) brewing method as described in this book. A ten gallon brewing system can be built in a couple of weekends. Bill Owens shows you: How to build a mash tun from a camping cooler. How to convert a beer keg into a kettle. How to construct a heat exchanger from a garden hose. How to control fermentation. This book explains how, on your first brew, you can produce wonderful, cold, clear and carbonated beers in just 10 days.
